Job Summary: This position is responsible for application-layer modeling and algorithm development for supercapacitor energy storage systems (CMS) supporting Peak Shaving and other high dynamic power scenarios. The role will build and validate equivalent circuit/system-level models, develop SOC/SOP/SOH (SOX) algorithms, perform parameter identification and calibration based on test data, and collaborate cross-functionally to support product development and system integration.
This position is sitting in China, serving global product development and business growth for supercapacitor energy storage applications.
Key Job Responsibilities:
• Develop application-layer models for supercapacitor energy storage systems (CMS), including system-level simulation models.
• Build equivalent circuit models (ECM) and dynamic characteristic models; develop parameter models for capacitance, ESR, temperature, and related factors.
• Design, develop, and validate SOX algorithms including SOC (State of Charge), SOP (State of Power), and SOH (State of Health) for supercapacitor applications.
• Implement and improve algorithms such as energy-based SOC estimation, online ESR identification, power boundary calculation, temperature compensation, aging models, and self-discharge compensation.
• Perform parameter extraction and model calibration based on experimental data; conduct online parameter identification (e.g., RLS/EKF/UKF) and analyse aging/consistency issues.
• Support testing and experimental validation; collaborate with cross-functional stakeholders to deliver modeling and algorithm solutions for Peak Shaving applications.
